Honestly, I love this approach, and I think it is the only right one to take when your team finished as the worst in the league last year. If you are on a poor roster, you should never feel secure. It promotes energy, effort, and focus of all the guys that come in.
And I love that they are bringing in so many different guys to see if they can help us more than just this game or just this year. I never understood why we weren't doing this every year, especially with the practice squad. Get closer looks at guys and you might find someone valuable.
